CMC lift failure

Welds breaking is no good at all
No excuses
Daily inspections
But as far as boom failure
For now IMO all speculation until report comes out
To much he said she said

I called OSHA they told me any indication of flawed design or bad batch of machines from the very beginning of a investigation they would ground all machines until investigation is complete
Time will tell
Are you saying you spoke with an OSHA Compliance Officer who said OSHA has the authority to "ground all machines"? Or that they would evaluate a company's engineering design of its product to determine if it's flawed or not? Or they would perform quality assurance for a private company? During the years I dealt with OSHA, they only wanted to see if we were in compliance with their regulations, possibly levy fines if we weren't and ensure corrective actions were taken to mitigate any non-compliances.

Yes I talked to personal at MIOSHA and they informed me that when they start any investigation into a accident and if there is any evidence of a machine had a design or bad batch of machines they will suspend that model or series until further investigation proves that they are safe
 
I stopped to speak with another local company that has the CMC 92HD, just to make sure they were aware of the current situation and had done an inspection. The guy I spoke to (low guy in the company, not the boss) said they had been contacted by CMC about a recall.

From the conversation I had with him, it'd be easy to see how info could be miscommunicated between him and his boss and then to me. So it's very possible that there is no recall at this point, or it could have been about a different issue entirely, if you other owners haven't heard about it. But maybe something to look into?

Unless MIOSHA has WAY more authority than (federal) OSHA, they don't have the legal authority to do that. They only have authority to do one thing: issue a citation. They don't even have legal authority to stop work in an imminent danger situation, although employers normally comply. To do anything beyond issuing a citation, they have to get a judge to issue a court order. That's not to say they can't make a recommendation. I believe you spoke with someone who is ill informed.

29 CFR 1926.453 Aerial Lifts incorporates by reference ANSI A92.2-1969 Vehicle Mounted Elevating and Rotating Work Platforms which provides guidance for manufacturers and dealers, so a basis for an enforcement activity exists; they could issue a citation.

They haven’t contacted me about any recall

Maybe mine wasn’t involved

MiOSHA is just Michigan’s division I supposed
I thought each state had their own division but yes federally controlled
And yes maybe I was misinformed but that is what I was told

I wish for the report to come out

anyone know how long they take

The Feds can "delegate" regulatory compliance enforcement to states, as long as the states enforce, at a minimum, the federal standards. In those cases, the state enforcement agencies are indeed state agencies, not part of the corresponding federal agency. In AL, EPA regulations are enforced by the state department of environmental management, but OSHA is enforced by (federal) OSHA.

Here we go again apparently I’m saying things that aren’t true by by repeating information I received from OSHA

Crazy
 
Well just received my email
They are showing two photos of the place to inspect
It’s on the upper boom bottom side
It’s where the cylinder for the extension on the bottom connects to the boom

if their is no cracks your fine
And then they want pictures of that area

Then they are willing to pay for a structural inspection if owner want to
Cracks no cracks they are willing to pay for a inspection
 
How quickly after that crack develops are you no longer fine? Did they advise on inspection frequency? You mentioned earlier 2-3x per day. Is that enough? Were there cracks observed on the failed units before they failed?

Good they are responding. Great they are offering to pay for the inspection. You gonna take them up on that?

Any lift or boom should be inspected everyday

Where they are telling you to inspect you should be daily
If there is a cracked weld anywhere the lift wouldn’t pass inspection period

Yes I will have a structural but not until May with my annual inspection

many lift or boom should be inspected every year (certified by a professional)

So I completed a app or form and had to take 10 different pictures and the app was really easy and walked me through every picture giving me a sample picture of each one

also serial number and hours
Now they are going to get ahold of me

No bad welds no worries
April 20 annual and structural inspection

Well 5 hours later and received a call from All Access saying my machine is fine
Continue running it but keep up the daily inspections
But update is coming
2nd time I heard an update is coming soon
I’m not going to name my 2nd source

appears to have a reinforcement plate around the base of the boom, that stops tight where it split, there should be a weld right there, welding = heat heat = metal having different properties, it seems that the weld had heated up the steel in that section of the boom, and caused some large differences in the grain structure, and possible cracking, from my observation, that weld is the issue
 
Friend sent me this from face crack. Pretty scary

Thanks for posting this story, and my sincere condolences go out to my fellow arborist and his family.

Recently, I was approached by a company with an offer of employment. The day after I spoke with this guy I get an update email from Treebuzz about what I had missed lately. This thread was the first thing that popped up.

This is important because he told me the night before I see this article about this 83’ lift they use. And apparently they rely on it pretty heavily. The company who approached me do not use progressive climbing techniques.

For me, to read this article while I was considering a job offer that, if accepted, would’ve seen me running this machine on the regular. This was providence.

I’m not bashing aerial lifts. However, I have been trained and indoctrinated in a healthy and progressive tree-climbing centric company. So this post along with some other, independent pieces of evidence helped me to realize that company was not a suitable move for me.

Might be worthwhile to at the very least let them know that you aren’t interested in the job and about this thread.
Who knows you might find some common ground, and might be a resource to each other?
